GEORGE M. NEWHALL, OF PHILADELPHIA, PENNSYLVANIA.

CONDENSER.

Specification of Letters Patent.

Patented Jan. 12, 1909.

Application filed January 2, 1907. Serial No. 350,333.

To all whom 'it may concern:

Be it known that I, Grenen M. NEWHALL, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Condensers, of which the following is a specification.

My invention relates to certain improvements in a condenser for which a patent was granted to me on the 13th day of March, 1906, No. 815,031.

rIhe object of my present invention is to so construct the condenser that the vapor will pass upwardly in a circuitous path through sprays of water and a further object is to insure the sealing of the several detlectors.

My invention also relates to certain irnproveinents in details which will be fully described hereafter.

In the accompanying drawings: Figure 1, is a longitudinal sectional view of my improved condenser; Fig. 2, is a transverse sectional view on the line 2 2, Fig. 1, and Figs. 3 and 4, are detailed views of the invention.

A is the shell of the condenser which is made quadrangular in cross section, as illustrated in Fig. 2.

a is the vapor inlet.

c is the air outlet connected in any suitable manner to the vacuum pump and c is the outlet in the bottom of the condenser communicating with the hot well. In front of a vapor inlet a is a vertical detlector a which extends down to a point near the bottom ot' the condenser, as indicated in Fig. l, and extending from this partition towards the opposite end of the condenser are horizontal partitions B B and between these partitions is a third partition B2 extending from the opposite end of the condenser tol a point near the detlector a, leaving space, however, for the passage of the vapor, as indicated by the arrows.

By arranging the partitions in the manner shown, the vapor is caused to travel in a circuitous passage through the condenser. First, by being directed by the deflector a to the lowest level of the condenser, passing under the partition B, then around the end of partition between itand the partition B2, and then around the end of this partition B2 between the partition B and the partition B, and finally around the partition B f and over said partition through the outlet c,

thus the vapor as it enters the condenser passes first down under the lowest partition and gradually works its way through the sprays of water to the upper portion of the condenser, passing out of the outlet c. By this arrangement the vapors first come in contact with the partially warmed water and as they near the top pass through the showers of cooler water. It will be understood that the water as it passes from one partition to another takes up a certain amount of heat from the vapors passing through the spray.

D is a water pipe having a longitudinal slot l in its upper part, which extends preferably throughout its entire length, and this pipe is connected to a water inlet D so that a. sheet of water will constantly How out through the slot cl in the pipe D, over the pipe down onto the horizontal partition B, passing through the partition B onto the partition B2 and finally onto the partition B through it to waste.

Each partition is made in two sections b and b and each section is composed of a series of troughs e, each having a low flange e at one side and a high ange e2 at the opposite side, which is curved over the low flange of an adjoining trough, the end of this flange extending below the edge ot' the low flange, so as to form a trap for the water, as indicated in Fig. 3. This construction is similar to that described in the abovementioned patent. The several troughs e are supported on'ribs j' projecting from the sides of the condenser casing A, as clearly illustrated in Fig. 2.

It will be seen that by providing two sets of trapped troughs, one directly below the other, that the water as it drops from one partition to the other, or from the pipe D onto the upper partition, cannot splash so as to break the trap of the lower set or' troughs as the upper set of troughs breaks the fall ot the water and the water will iiow over the lower flanges e of the upper set of troughs falling gently into the troughs directly below it, thus insuring a water seal to prevent the passage of air through the partitions.

It will be noticed in referring to Fig. l that there is an opening a2 in the detlector a and this is closed by a plate a3 secured in place by bolts and nuts at. In some instances it may be desirable to remove the said plate a3, or so adjust it as to allow a certain amount of vapor to pass directly through the opening a2 in order to prevent back pressure. In some instances spacing blocks z' may be used'between the deflector aand the plate a, as illustrated in Fig. 4.l

`instance, which extend through the deector a to the opposite end of the condenser, and valves are provided to regulate the flow of gas through the pipes. By this arrangement the uncondensable gases will not interfere with the flow of vapor through the condenser. On each side of the Vcasing of the condenser are vertical deflectors f', which prevent the vapor passing around the show ers from the several horizontal positions.

and travels upwardly in a serpentine hot well.

The operation of my improved condenser is as follows: The vapor passes through the inlet o )ening a and 1s caused to pass down to the lower portion of the condenser by the deflector a and under the partition B ath around the partitions B, B2 and B an out through the openings c at the upper end of the condenser; the water passing out of the condenser through the opening c to the The water as it passes from the pipe D sprays onto the upper portion of the casing and over the sides of the pipe down in a thinf'sheet onto the partition B and fills the several troughs e, overflowing the upper set of troughs down to the lower set and passing in thin sheets down onto the partition B2 and from this partition yonto the partition B. Thus the vapor, as in the patent above mentioned, must pass through -numerous thin sheets or sprays of water before it can pass from the condenser, consequently a nearly complete condensation of the exhaust steam or other vapor takes place before it reaches the outlet.

I claim- 1. The combination in a condenser, of ay casing, a series of horizontally arranged' trapped partitions extending alternately from the ends of the casing so as to form aV circuitous passage therethrough and each consisting of a plurality of closely adjacent sections one above the other, a vapor inlet communicating with the lower portion of the condenser, an outlet communicating with the upper end thereof so that all the vapor will pass under and over the partitions, and a water supply situated above the partitions, the water passing through the several partitions, substantially as described.

2. The combination in a condenser, of a casing, a horizontal partition mounted within the casing, an inlet for vapor on one side of the partition, and an outlet on the op- Vpo'site side thereof, said partition consistin of two sections each made of a series o trapped troughs, said sections beingimmediately adjacent to each other and one being directly below the other, with means for supplying the upperset of troughs with water, the troughs of the upper section being arranged to overflow into those of, the lower section without causing breakage of the water seal of the troughs of the latter section.

3. The combination in a condenser, of a casing, an inlet for vapor and an outlet, a. series of horizontal partitions so arranged that the vapor will pass through the condenser in a serpentine path, a water inlet in the upper portion of the condenser, each partitlon consisting of two sets of trapped troughs, one mounted directly below the other so that the splash of the water falling onto the upper trough will not Vbreak the seal in the lower trough, substantially as described. Y

4. The combination in a condenser, of a casing having an inlet for vapor at one end, a vertical dellector extending down in front of the inlet to a point near the bottom of the condenser and extending from one side of theJ condenser to the other so that the vapor.

must pass under the deiector, an outlet for vapor on the opposite side of the deilector, a horizontally arranged Water pipe in the upper part of the condenser, and a series of horizontally arranged partitions, each partition consisting o a lurality of trap edV troughs arranged one a ove thel other so t iat the vapor must pass down to the bottom of the condenser and travel through the space between the partitions, substantially as described.

5. The combination in a condenser, of an inlet at one end of the condenser, a vertical deflector extending down in front ofthe inlet to a point near the bottom of the condenser, an outlet on the opposite side of the partition, a series of horizontally arranged trapped partitions in the condenser, an opening 1n the vertical partition, and a detachable plate secured to the partition and covering said opening, substantially as described.

6. The combination in a condenser, of a. casing, an inlet in one end of the casing, a vertical deflector in front of said inlet and extending to a point near the bottom of the condenser, a series of horizontal partitions mounted between thevertical partition and the o posite end of the casing, each horizontalJ partition being made up of two series of trapped troughs, said partitions stopping alternately at a point near one end of thecasing sothat the vapor after it passes under the vertical deflector will pass in a serpentine path between the lseveral horizontal partitions and through parallel showers of water escaping from one partition to the other, a pipe in the upper end of the condenser having a. slot in its upper edge so that a film of Water will pass from the pipe onto the upper partition, substantially as described.

7. The combination in a condenser, of a vertical de'tleotor extending to a pointl near the bottom or" the condenser, an inlet for vapor on one side of the deliector, and an outlet at the other side thereof, a series of horizontally arranged partitions, each partition consisting of a series of trapped troughs,

a. Water supply pipe above the upper partition, a relief pipe extending through the vertical detlector to a point at the opposite 15 end of the condenser, and a valve in said pipe, substantiallv as described.

ln testimony whereof, l have signed my name to this specification, in the presence of two subscribing Witnesses.
